Telegram is another app, that, like Signal, puts a huge premium on user security and privacy. While it may not be as popular around the world as some of the other apps on this list, it’s still got a strong following in certain parts of the world. These include Iran, Uzbekistan, and Ethiopia.
You can share files with other Telegram users, write messages, and make voice calls. All of these features boast strong end-to-end encryption, too.
As with LINE, Telegram isn’t only a mobile app either. If you’d prefer, you can install it on Windows, macOS, and even Linux too!
